Technical Field
[0001] This utility model relates to the technical field of shelving equipment for warehousing and logistics, and in particular to a shelving system for cold chain warehousing and logistics. Background Technology
[0002] Cold chain warehousing and logistics generally refers to a systematic project that ensures refrigerated and frozen foods are kept in a specified low-temperature environment throughout all stages from production, storage, transportation, and sales to consumption, in order to guarantee food quality and reduce food loss.
[0003] Shelving is essential for cold chain warehousing, serving as a crucial tool for improving warehouse efficiency. Existing patent CN202022552938.8 proposes a smart warehousing modular shelving system. However, this solution suffers from several drawbacks. Firstly, the spacing between shelf panels is inconvenient. For larger items, the limited space between shelves prevents storage, while for smaller items, it results in low space utilization. Secondly, the existing system only provides baffles on the left and right sides of the shelf, lacking anti-fall mechanisms at the front and rear access points, posing a risk of goods slipping.
[0004] In view of the above problems, a cold chain warehousing and logistics rack is designed to improve the safety of goods storage and make it easy to adjust the spacing between the placement boards. Utility Model Content
[0005] In view of the above-mentioned technical problems, this utility model provides a cold chain warehousing and logistics rack. The placement panels are installed on the support frame in an easy-to-disassemble manner, so as to facilitate the adjustment of the spacing of the placement panel components according to the usage requirements. The front and rear sides of the placement panels are equipped with protective components to prevent goods from falling, and the left and right sides of the support frame are equipped with guard bars to improve the safety of goods storage.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows:
[0007] A cold chain warehousing and logistics rack is characterized by comprising a support frame and placement panels. Multiple placement panels are mounted on the support frame, and the placement panels are easily detached and installed on the support frame via fixing components. The fixing components are disposed on the placement panels. Anti-fall-off protective components are provided on the front and rear sides of each placement panel. Multiple rollers are arranged at intervals within mounting grooves on the placement panels to facilitate the loading, unloading, and movement of goods. The rollers are fitted onto a central shaft, and both ends of the central shaft are fixed to the groove walls.
[0008] The support frame consists of a front support rod and a rear support rod. The front support rod has multiple sets of fixing slots spaced apart, and the rear support rod has multiple sets of limiting slots spaced apart. The front ends of the placement plate are respectively connected to the fixing slots on the front support rod, and the fixing components are connected to the fixing holes on the fixing slots. The rear ends of the placement plate are respectively inserted into the limiting slots on the rear support rod.
[0009] The fixing assembly comprises a handle, helical teeth A and B, a bidirectional lead screw, a moving rod, and a fixed post. The two ends of the bidirectional lead screw are mounted in the inner cavity of the placement plate via bearings. The bidirectional lead screw is provided with helical teeth A, which meshes with helical teeth B. Helical teeth B are connected to the handle via a connecting shaft. The two ends of the bidirectional lead screw are respectively threaded to the moving rod, and the moving rod is connected to the fixed post.
[0010] The fixing column is adapted to the fixing hole provided on the fixing groove.
[0011] The protective assembly consists of a rotating plate, a lifting spring, and a fixing block. The rear end of the rotating plate is mounted in a groove on the placement plate via a rotating shaft. The front end of the rotating plate is provided with a lifting spring, and the front end of the rotating plate is tilted upwards and protrudes from the groove opening due to the lifting spring. The other end of the lifting spring is fixed to the fixing block, and the fixing block is fixedly set in the groove.
[0012] Furthermore, the support frame is provided with baffles on both sides, which are fixed to the support frame with screws. The baffles reduce the possibility of goods falling from the left and right sides of the support frame.
[0013] Furthermore, the bottom of the front support rod and the rear support rod are provided with a fixed base, and the fixed base is provided with mounting holes for fixing the shelf.
[0014] The beneficial effects of this utility model are:
[0015] This utility model features multiple sets of limiting grooves and fixing grooves arranged at intervals on the front and rear support rods of the support frame, facilitating quick positioning and installation of the placement plate. Fixing components are provided on both sides of the front end of the placement plate to enable easy disassembly and assembly. The up-and-down movement of the two sets of fixing columns is controlled by operating a rotary handle. When the fixing column extends into the fixing hole of the fixing groove, the placement plate is fixed. When the fixing column moves down and out of the fixing hole, the placement plate can be disassembled, allowing for easy adjustment of the spacing between the placement plates according to usage requirements, thus improving the practicality of the shelving.
[0016] This utility model has protective components on the front and rear sides of the placement plate to prevent goods from falling. When goods are placed on the placement plate, they move and press against the rotating plate, which compresses the lifting spring. The rotating plate rotates until it is flush with the groove opening, and the goods can be placed smoothly on the placement plate. After the goods are removed from the rotating plate, the lifting spring returns to its original position, causing the front end of the rotating plate to be lifted and tilted. The front end of the rotating plate is higher than the groove opening, thus effectively protecting both the front and rear sides of the goods and improving the safety of goods storage.

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0026] Example 1
[0027] As shown in the figure, the support frame consists of a front support rod 11 and a rear support rod 12. Multiple sets of fixing grooves 111 are arranged at intervals on the front support rod 11, and multiple sets of limiting grooves 121 are arranged at intervals on the rear support rod 12. The placement plate 3 is installed on the support frame so that the placement plate 3 passes through the fixing groove 111 on the front support rod 11 and extends into the limiting groove 121 of the rear support rod 12. The front two ends of the placement plate 3 are respectively located in the fixing groove 111 on the front support rod 11 and are connected to the fixing hole 112 provided on the fixing groove 111 through the fixing component on the placement plate 3. The rear two ends of the placement plate 3 are respectively snapped into the limiting groove 121 provided on the rear support rod 12.
[0028] Multiple sets of baffles 21 are provided on both sides of the support frame. The baffles 21 are fixed to the support frame with screws to reduce the possibility of goods falling from the left and right sides of the support frame. In addition, fixed bases 22 are provided at the bottom of the front support rod 11 and the rear support rod 12. The fixed bases 22 are provided with mounting holes for fixing the rack.
[0029] like Figure 2 and 4The two ends of the bidirectional lead screw 34 in the fixed assembly are mounted in the inner cavity of the placement plate 3 by bearings. The bidirectional lead screw 34 is provided with helical teeth A (33), which mesh with helical teeth B (32). Helical teeth B (32) are connected to the handle 31 through the connecting shaft. The threads on both sides of the bidirectional lead screw 34 are in opposite directions. Moving rods 35 are threaded to both ends of the bidirectional lead screw 34. The moving rods 35 are connected to the fixed post 36. The fixed post 36 is located in the moving groove provided on the placement plate 3, and the fixed post 36 is adapted to the fixed hole 112 provided on the fixed groove 111.
[0030] like Figure 2 and 3 Multiple rollers 51 are arranged at intervals in the mounting groove on the placement plate 3 to facilitate the handling and movement of goods. The rollers 51 are mounted on a central shaft 52, allowing the rollers 51 to rotate around the central shaft 52. The two ends of the central shaft 52 are fixed to the groove wall of the mounting groove on the placement plate 3. This ensures that when goods are placed on or off the placement plate 3, the bottom of the goods contacts the rollers 51, resulting in less rolling friction than sliding friction, thus requiring less effort when handling goods.
[0031] like Figure 3 and 5 The front and rear sides of the placement plate 3 are equipped with anti-fall protection components. The protection components consist of a rotating plate 61, a lifting spring 63, and a fixing block 64. The rear end of the rotating plate 61 is installed in the groove 31 on the placement plate 3 through a rotating shaft 62, so that the rotating plate 61 can rotate in the groove 31 with the rotating shaft 62 as the axis. The front end of the rotating plate 61 is provided with a lifting spring 63. The lifting spring 63 gives the rotating plate 61 an upward force, so that the front end of the rotating plate 61 tilts upward, making the front end of the rotating plate 61 higher than the opening of the groove 31. The other end of the lifting spring 63 is fixed to the fixing block 64, and the fixing block 64 is fixedly set in the groove 31.
[0032] Example 2
[0033] When it is necessary to adjust the spacing between adjacent placement plates 3, the placement plates 3 are removed and inserted into the fixing slots 111 and limiting slots 121 corresponding to different heights. The fixing components for fixing the placement plates 3 are easy to operate. By operating the handle 41, the bidirectional lead screw 44 is rotated, causing the two sets of fixing posts 46 to move in opposite directions simultaneously. When the fixing post 46 extends into the fixing hole 112 of the fixing slot 111, the placement plate 3 is fixed and limited. When the fixing post 46 moves out of the fixing hole 112 and returns to the placement plate 3, the placement plate 3 can be disassembled and removed. This allows for easy adjustment of the spacing between the placement plates according to usage requirements, improving the practicality of the shelving. In addition, the handle 41 for operating the fixing components is set on the vertical surface of the placement plate 3, which does not occupy the placement surface of the placement plate 3, avoiding problems that affect the placement of goods.
[0034] When goods are placed on the placement plate 3, as the goods move and press against the rotating plate 61, the lifting spring 63 is compressed, and the rotating plate 61 rotates until it is flush with the groove opening, allowing the goods to be placed smoothly on the placement plate 3. Once the goods are no longer pressing against the rotating plate 61, i.e., after the goods have been placed, the lifting spring 63 returns to its original position and continues to push the rotating plate 61 upwards, causing the front end of the rotating plate 61 to be lifted and tilted, with the front end of the rotating plate 61 extending above the groove opening of the groove 31. This blocks the path of the goods moving forward and backward, effectively protecting both the front and back sides of the goods and improving the safety of the goods storage.
